java - 如何将客户端发送的Base64图像存储在BlobStore中

Question

我对 BlobStore 非常陌生，我从客户端收到 Base64 图像我这样转换它:

byte [] picByte = Base64.decodeBase64(pic);
Blob blob = new Blob(picByte);

我正在使用 jersey 2，我的目标是保存这张图片并稍后获取服务链接 blobstoreService.serve

如何保存这张带有 Jersey 2 的图像？谢谢，

Answer 1

    byte[] picByte = Base64.decodeBase64(pic);
    GcsFileOptions instance = new GcsFileOptions.Builder().mimeType("image/jpeg").build();
    GcsFilename fileName = new GcsFilename("xxx-app.appspot.com", "someName.jpg");
    GcsOutputChannel outputChannel;
    GcsService gcsService = GcsServiceFactory.createGcsService();
    outputChannel = gcsService.createOrReplace(fileName, instance);
    ByteBuffer a = ByteBuffer.wrap(picByte);
    outputChannel.write(a);
    outputChannel.close();
